To rill .whom may concern...

Be-it known that I, JOHN BLUE, of Covert, in the county of Seneca andState of New Yorkflaave invented a new and useful 1m 'provement inHarvesters; and I do hereby declare that the following is a full, clear,and exact'description of ,my said improvement,

.' and of-the manner of making, constructing,

and-iising the same, reference being'had to the'acoompanying drawing,making a part of this'specification, in which my improvement isrepresented.

. "llhe object of. my invention is to enable the driver inthe'seat ofthe machine, while in cutting motion, easily to adjust the elevation ofthe reel to the variable conditions of thegrass "and grain through whichthe machine moves.

. It consists 'in. combining a knee-joint, hav

ing a spring catch in :other device for holding the jointin positionuponone of finele'vers forming the joint, with reel-standards hinged onbearings ofhooks or bolts arranged in line with the shaftof" the wheeldirectly driving the. reel, .for g the purpose of permitting themovement'bfthe standardson thehin'ge with:

o'ut'derang ing the band or gear driving the hinged;on ;hoox's arrangedin line withthe shaft of the wheel which directly drives the .reel,andeombin'ed with a knee-joint having asp'ring catch upon one of thelevers formingthesamefor-actuating the hinge, representsinvi'mprovement. the frame of drivingjthe 're'el-;-G, this-wheel; D, thepulley directly driven b'y'the'wheel o; n, the reel;-

1 he hook'sarranged in line with the shaftB,

on-which' hooksthe loops g g hinge.

'f'Myi nprovement is made and-constructed by niakingfa reel" in thecommon way with twobearings on one projectingend of its shaft, as. farapart. assconvenient for its adaptation as repreoutsid'esof' thehearings on the shaft of the to need description.

Wheeldirectly the-hinge-loop i P5.

reel, and corresponding boxes are made in the standards, as representedby the cross-brace j and the standards f f. A loop of iron is bent and"bolted over the lower end of each of these standards, .leavingsufficient space for a hook parallel with the shaft of the reel. Theseloops are hinged upon bolts or books arranged rectly drives .the reel,as represented by the same for the shaft to turn in, as represented 'bythe hooks It 7. each of which serves for both hook-and. box; 'but incase, as in other to the frameand thewheel turns thereon, the

"length'mdicates; of theboitls for the'loops to 'not to occupy't-heplace for the bolt orhook, the same is center.

Foractuating the hinge, a catch-lever with an ordinary spring pin orcatch, and a corresponding circular plate of correspondingpin holes ornotches, fo rming,with another level", a'knee-joint, is attached to thestandard next to the reel, as represented by the lever h, knee joint i,spring-pin n, and circular plate p.

Motion is communicated tothe wheel 0 by tion to such wheels, which aretoo well known 1 -My improvement is used by straightening the joint i,in raising. the lever h, whenever the elevationof the reel is desired,and flexing thisjoin't in lowering depression is desired; I do not claimthe devices employed, for they have been used in different arrangementin the harvesting-machine; but

- What I-elaim as my invention, and desire to secure by-LettersPatent,is'- v The combination of the knee-joint i with the reel-standards ff,shaft B, and bearings-k k,
